James said this because there was a famine going on and christens were not sending money to the church of Jerusalem. “People were starving” So yes their faith was useless, he was not saying they were not saved! Here is something for you to think about.
Mark-5:13
5Then the Pharisees and scribes asked him, Why walk not thy disciples according to the tradition of the elders, but eat bread with unwashen hands?
6He answered and said unto them, Well hath Esaias prophesied of you hypocrites, as it is written, This people honoureth me with their lips, but their heart is far from me.
7Howbeit in vain do they worship me, teaching for doctrines the commandments of men.
8For laying aside the commandment of God, ye hold the tradition of men, as the washing of pots and cups: and many other such like things ye do.
9And he said unto them, Full well ye reject the commandment of God, that ye may keep your own tradition.
10For Moses said, Honour thy father and thy mother; and, Whoso curseth father or mother, let him die the death:
11But ye say, If a man shall say to his father or mother, It is Corban, that is to say, a gift, by whatsoever thou mightest be profited by me; he shall be free.
12And ye suffer him no more to do ought for his father or his mother;
13Making the word of God of none effect through your tradition, which ye have delivered: and many such like things do ye.
Even if thats the reason James says it, its still truth. Just as its true when paul says we're not justified by works but faith. He had a reason too. He was talking to unbelieving Jews teaching Circumcision and to those they caused to stumble in faith.
And please think about this also:
The commandments im talking about are taught by Jesus and His apostles. They're commandments of Christ
Paul also said:
Tit 3:8 This is a faithful saying, and these things I will that thou affirm constantly, that they which have believed in God might be careful to
maintain good works. These things are good and profitable unto men.
Heb 10:24 And let us consider one another to provoke
unto love and to good works
Tit 3:14 And let ours also learn to
maintain good works for necessary uses, that they be not unfruitful.
Tit 2:6 Young men likewise exhort to be sober minded.
Tit 2:7
In all things shewing thyself a pattern of good works: in doctrine shewing uncorruptness, gravity, sincerity,
Tit 1:16 They profess that they know God; but in
works they deny him, being abominable, and disobedient, and unto every good work reprobate
Eph 2:10 For we are his workmanship, created in Christ Jesus
unto good works, which God hath before ordained that we should walk in them.
1Ti 6:17 Charge them that are rich in this world, that they be not highminded, nor trust in uncertain riches, but in the living God, who giveth us richly all things to enjoy;
1Ti 6:18 That they do good, t
hat they be rich in good works, ready to distribute, willing to communicate
2Ti 3:17 That the man of God may be perfect, throughly furnished unto all
good works
